[PATCH v15 01/12] package_rpm.bbclass: Drop external dependency generator to support rpm 6

[Sumanth Gavini <sumanth.gavini@windriver.com>]

The rpm 6 doesn't support external dependency generator. Oe-core used it for
per file dependency which was saved into pn.requires and pn.provides,but that
hasn't been used any more since 2012 (rev:
be40f6d0bb80274366af00461112af65687a4de8), and there were no complains or
updates in the past 13 years, so just drop it to support rpm 6.
